The bond length between double bonded carbon atoms is?

Correct Answer: A. 1.34A˚

he bond length between double-bonded carbon atoms is approximately: 1.34 Å (Angstroms)
The typical bond length for a double bond between carbon atoms in a molecule like ethene (C2H4) is approximately 1.34 Å. This value may vary slightly depending on the specific molecules involved, but 1.34 Å is a reasonable estimate for a double bond between carbon atoms.
